sql重置数据库表所有标识列

数据库同步之后，数据库标识列从1开始计数，使用以下语句重置所有数据表的标识列。

declare c_a cursor for SELECT name FROM sys.sysobjects WHERE type='U';

declare @id nvarchar(100);
declare @sql nvarchar(1000);
open c_a;


fetch next from c_a into @id;
while @@fetch_status=0
begin
   set @sql='DBCC CHECKIDENT ("'+@id+'", RESEED)';
   exec sp_executesql @sql
   fetch next from c_a into @id;
end;
close c_a;
deallocate c_a;
